Cm2250 overfueling intermittently

monitor engine data and catch it when it switches between good and bad?.


- Sometimes it is the not so obvious. For example, I had a truck here yesterday that had low fuel mileage for 2 years, high 4's and low 5's even though the driver was babying the hell out of it. It had been to several places to have it looked at. 5 minutes of it being here, I found the thermostat housing passage for the exhaust back-pressure sensor was 100% blocked up so badly, I had to take a coat hanger and dig it free.

No codes at all on dash.
